Firefox will not display, and It appears that there is an incompatible program installed.

How do I locate and remove incompatible programs that are preventing Firefox from displaying on my screen? I have the latest Firefox program installed, but I cannot get it onscreen. I ha ve removed Babylon, or at least I have performed the recommended steps to remove it and it no longer appears on my computer's list of installed programs. However, I still cannot retrieve Firefox on my screen. I am using Googlechrome instead as my browser but it doesn't match Firefox for ease and convenience.

hello ralph, does it work when you press the shift key while launching firefox in order to access firefox safemode - then you can do a reset to revert most of the settings to the factory default.

  • I have downloaded the HD version of a movie from itunes, but when I sync it to my iPad 2 it will not play. It appears that it is on the iPad, but it will not play. Is this because it is HD, and if so is there a way to change it from being HD? Thanks

    I'm having a similar problem ... just used my iPad 2 to purchase the Bourne trilogy and it downloaded fine but I did not try to play it right away.  Then I plugged the iPad into the computer and it downloaded the SD versions of the movie and I used iTunes to sync my movies.  Then I tried to play it and it said it could not open the movie.  I then did a full iPad restore and did a fresh sync and now I get the Cannot Opne pop up.  Did you ever find an answer to your question?

  • Firefox will not display on the screen even though with Process Explorer I see Firefox.exe active but no CPU usage

    I use Firefox v10.0.2 as default browser on Dell XPS8300 e/w Intel Core i5 & Windows 7 Ultimate and Compaq Presario CQ57 e/w Intel Core i3 & Windows 7 Home. More frequently on the (about 90% of attempts) than the Dell (50% of attempts) Firefox will not display to the screen when I click on icon. When it happens I cannot display other programs. I specifically say display because I believe Firefox has started. To circumvent the problem I installed Process Explorer on both machines and start this program first then click on Firefox icon. When problem occurs I can see Firefox.exe process in Process list; some CPU consumed but, then, no CPU activity. If I click on Firefox icon again another process opens in Process list but with same response - some CPU consumed and then no CPU activity. If I have 2 processes running and kill the 1st process, the 2nd will display and everything from then on is normal. If I do not open a 2nd process but kill the 1st process then click on Firefox icon Firefox is displayed and everything from then on is normal. This problem has occurred since original installation on both new machines. I've updated video drivers in both machines.

    Ok, let's see if we can fix this and get it working for you!
    First, if you start Firefox in [[safe mode|safe mode]] (restart your computer first, then when you open Firefox, hold down the shift key) does it start up more reliably? This is usually caused by a faulty add-on. If it does help, then restart Firefox, go into the Firefox button, then add-ons, and disable your extensions one by one until you find the trouble maker.
    Also, try updating to Firefox 11, it has several bug fixes that might make life easier here.
    Just as a few basic troubleshooting steps to make sure we have all the bases covered,
    Run all Windows Updates, install all needed service packs, etc.
    Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
    Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. you can uninstall this program after you clean off any infections.

  • Updated to the latest revision. Firefox will not display my chosen home page without clicking on home icon.

    Since latest update...Firefox will not allow a new page to be opened from a link in a current page. It will allow a new tab to be opened (with tabbed browsing checked) but i prefer a new page. Even in tabbed browsing links to things like a pdf will not work at all.
    Firefox WILL NOT close. X-ing out will close the window but I can not get back to Firefox without closing it in task manager.
    Firefox will not display my chosen home page without clicking on home icon.

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • Firefox will not display videos since Yosemite migration

    Good day!
    I run an early 2011 15" MacBook Pro, 2,2 GHz Intel Core i7 with 4g 1333 MHz DDR3 Memory, and an Intel HD Graphics 3000 with 384 Mo. Firefox is 34.0.5.
    Since I migrated to Yosemite (10.10.1), the browser I use (Firefox) will not display the videos, but plays the sound out of them...
    I tried to clear the PRAM (NVRAM) with the Command (⌘), Option, P, and R, but it doesn't work. I even tried to shut down the graphic acceleration option in Firefox, to no avail...
    What else should I do? Any solution out there?
    Thanks, and Merry Christmas to you all!

  • Firefox will not display basic content on certain (common) sites

    Hi there:
    On certain websites (common) ones Firefox will not display options on the website.
    These sites include Yahoo Mail, Twitter, Weebly.
    An example would be if there is a menu of choices such as delete, ad, tweet, etc. instead of displaying correctly it looks like a box with 4 dots.
    The other browsers are fine. I have the latest Firefox and this started with the previous version as well. I uninstalled/reinstalled without change.
    Windows 7 Computer/Norton Anti Virus.
    If allowed I can upload a screen shot.
    Thank you.

    > But I really don't want to allow all sites to use
    > their own fonts, just, in this case, Twitter.
    Exactly. It's not a very good solution to be forced to give up control/accessibility on every Web site, to fix a problem with just a few popular ones like Twitter.
    It seems like a pathetic accessibility fail on the part of Yahoo, Twitter, etc., but since the practice is likely to persist and spread, please, Firefox:
    => allow site-specific configuration of "allow pages to choose their fonts."

  • Firefox will not start and open a website from a Thunderbird email link. It will go to a link from Thunderbird once Firefox is open, but will not initially start Firefox and proceed to open the Thunderbird email link.

    Firefox will not ''start'' and open a website from a Thunderbird email link. A link from Thunderbird will open once Firefox is ''already'' started, but will not initially start Firefox and proceed to open the Thunderbird email link.

    I also have this problem. I cannot open links from a discussion board I frequent nor can I open links from my email. Also after opening my email, I cannot go to any other sites except my home page. I can then go no where else.
    When I close Firefox and try to reopen it, it does nothing! I have to bring up the Task Manager and end the Firefox process before I can get back in.
    To the best of my knowledge, this problem started with the new update to Ver. 3.6.9. I am running Windows XP Media Center 2005

  • Firefox will not display Yahoo Calendar.

    Firefox will not display Yahoo Calendar (I have tried on four separate computers).
    When I use Internet Explorer, the Yahoo Calendar does display fine.
    Do you know why Yahoo Calendar will not display in Firefox? Is there any solution?

    Are you using Firefox 3.5? I am not sure whether Yahoo Toolbar still supports it.. Have you considered upgrading to Firefox 3.6.x or Firefox 5.0? :)

  • After loading the latest Aperture 3 update, aperture will not load and it appears to have corrupted 10.6.  10.6.7 now appears to be missing from the computer and my administrator status has changed to standard.

    After loading the latest Aperture 3 update, aperture will not load and it appears to have corrupted 10.6.7. and now appears to be missing from the computer and my administrator status has changed to standard.  Update Software says I need to do update to 10.6.7 which I can't do because administrator privileges are gone.   I didn't back-up with Time Machine ,BAD, but I have all files backed-up on another hard drive.  Should I just reformat and start over?  Any ideas or help would be appreciated.

    PROBLEM SOLVED! For me at least!
    Apple Support gave me the clue - I had run Migration Assistant, and it had obligingly replaced a system file (/Library/Frameworks/PluginManager.framework/Versions/B/PluginManager) with the equivalent from my old system.
    I reinstalled 10.6.7 using the DVD supplied and all is well.
    The moral is - don't use Migration Assistant.
    Along the way Apple Support provided me with a link to download Combo update 10.6.7: this could not be installed on my iMac.
    Hope this helps.

  • Firefox will not display characters that were added by the webmaster on user PC?

    I employed a company to design a site for me which is great. Then I asked them to add a small button/image in the back end (admin area) that when clicked on will send an email. No image will display so I got them to change it to Text format, still it is not showing on my end. The design company are able to send me emails showing where it is but I cannot see it. It is worthwhile mentioning that it will not display in either IE8 or Opera, Is it a firewall problem ? Or a setting on Windows 7?

  • Firefox will not display my photo website properly nor play the music from it on my new computer. I have 2 other PCs and it works fine on those.

    Just set up a new PC and downloaded Firefox. It will not display my Zenfolio Photo website correctly nor will it play the music that accompanies the main page slideshow. I have 2 other PCs and it works fine on them. All are Windows 7 Home Premium.

    Note that there is nothing wrong with setting Flash to "Ask to Activate" and click the Lego block icon on the Navigation Toolbar to activate the Flash plugin when needed.
    You can verify on the Adobe Flash Players Test Page that the Flash plugin is working and which version you have once you have installed the plugin and checked the setting in "Firefox/Tools > Add-ons > Plugins"

  • Firefox will not display certain features of websites in windows 8.1

    I've upgraded to windows 8.1. Installed Firefox (now ver. 26) right away. I go to the same websites to pay bills, do work stuff etc for the past few years.
    Those websites work fine most of the time. RANDOMLY (at least to me) 2 websites have been giving me trouble for certain features:
    1. Banking website will not display my online bill pay. It does not crash, it just says "unable to display page" and for me to check my firewall etc, reload page, etc. When I go to other features for my bank, it works fine except for the bill pay.
    2. My work website has a feature to display paychecks etc. It give me the same message of "unable to display".
    Here's the weird thing: I open and close firefox a few times and the page "magically" works.
    I load the same page in IE 11 and I have the same problem.
    I load the same page in chrome 32.0.1700.107m and I never have this problem.
    I load the same pages in firefox ver. 26 on a windows 7 machine and it work just fine.
    I'm at a loss since Firefox is my primary browser and only have the other browsers for the occasional incompatibilities.
    Any ideas? I've concluded that it's a windows 8.1 issue/compatibility but would like to try other solutions before I downgrade back to windows 7.
    FYI: I've turned off windows firewall and the same issue still occurs. I've updated to the latest adobe flash, shockwave, and Java. I only have one extension installed - adblocker (which is disabled for these websites).
    Thanks in advance for any help.

    Current Firefox versions have enabled a built-in PDF Viewer that doesn't have all features that other PDF readers like the Adobe Reader have or may not function properly otherwise.
    You can change the action for Portable Document Format (PDF) from Preview in Firefox to use another application like the Adobe Reader or set to Always Ask in "Firefox > Options/Preferences > Applications".
    You can set the pdfjs.disabled pref to true on the <b>about:config</b> page to disable the build-in PDF viewer.
    You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu if you want to display PDF documents in Firefox with another application (i.e. not the built-in PDF Viewer).

    Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

  • Firefox OS is not displaying correctly. it appears that the CSS and JS are not rendering! Any help would be most appreciated!

    I would have preferred to show anyone a screenshot of the web pages, but there is not an attach file on this forum. Anyway, with only Firefox OS , not my other browsers, the web pages are not rendering correctly. For example on Facebook there is no header or footer. JS is active in the browser and as I said Chrome and Safari are NOT having any problems. I am surmising that the CSS and JS files are somehow not being displayed. I may be very wrong, but I would gratefully accept any help someone has to offer. Thank you and have a great day!
